What this page needs

Runs in your browserJavaScript + CSSAPI-ready

This tool computes entirely on your device, so nothing you type is sent anywhere. That local computation needs JavaScript; CSS is used for layout and theming.

This tool is built to also work over an HTTP API. Processing is currently off, so the API is documented but not served; when it is switched on, you will be able to call it without a browser.
